Here's a link to the Card Candy gallery, but it also includes punch art.

As far as searching for phrases instead of single words in the gallery, I always use Google for that. The string to copy into Google's search box would be something like this, including the quote marks:
"card candy" site:splitcoaststampers.com/gallery
The main problem with using Google is that it doesn't show the thumbnails with its search results. But it's super fast.
